[0031] Please see the attached Figure 1-3In one embodiment, the present invention provides a public toilet permeable water recycling system, comprising a partition wall 30 and a permeable unit 10 and a water utilization unit 20 arranged on both sides of the partition wall 30. A connecting channel 310 is provided at the bottom of the partition wall 30, and the surface of the permeable unit 10 is connected to the surface of the water utilization unit 20 through the connecting channel 310. First of all, it should be noted that the longitudinal direction in this application refers to the length extension direction of the collection tank 120, and the transverse direction refers to the width direction of the collection tank 120; and different from the prior art where the ground is impermeable, when there is a large flow of people and in humid weather, water easily accumulates on the ground, resulting in mud and stains, breeding bacteria and dirt, and affecting the overall sanitary environment, and the toilet is an indoor closed environment. Once water accumulates on the ground, it is usually difficult to drain quickly. The accumulated water on the ground easily causes people of different ages to slip, causing physical injury or property loss, and the water is not reused, which is not conducive to the conservation and recycling of water resources. The present application solves the above-mentioned defects in the prior art by setting up a public toilet permeable water recycling system, as follows:

[0032] The permeable unit 10 includes a permeable layer 110 and a collection tank 120 with an opening at the top. The permeable layer 110 is laid above the collection tank 120. The collection tank 120 has a water collection space, and the collection tank 120 has a water outlet 122 at one end along the longitudinal direction; the water utilization unit 20 includes a water spray assembly 210 and a water treatment mechanism 220 built into the ground. The water outlet 122 is connected to one side of the water treatment mechanism 220, the first end of the water spray assembly 210 is connected to the other side of the water treatment mechanism 220, and the second end of the water spray assembly 210 extends out of the ground.

[0033] Specifically, the public toilet permeable water recycling system in the present application includes a partition wall 30, a permeable unit 10 and a water utilization unit 20. The partition wall 30 is used to separate the permeable unit 10 and the water utilization unit 20 on both sides. The permeable unit 10 is arranged in the public toilet and is used to absorb accumulated water on the indoor floor. The water utilization unit 20 is used to process the water absorbed by the permeable unit 10 for reuse; a connecting channel 310 is provided at the bottom of the partition wall 30, and the connecting channel 310 is used to connect the permeable unit 10 and the water utilization unit 20 from the ground, so that the accumulated water that is spilled on the surface of the permeable unit 10 and is not absorbed in time can also flow into the water utilization unit 20 through the connecting channel 310, playing an auxiliary role.

[0034] The water-permeable unit 10 comprises a water-permeable layer 110 and a collecting groove 120, the water-permeable layer 110 is used for absorbing accumulated water, has good water permeability, can make the water on the surface penetrate downward through the water-permeable layer 110, thereby flowing into the collecting groove 120, and the collecting groove 120 has a water storage space for storing accumulated water, therefore the water-permeable layer 110 is laid on the collecting groove 120; further, in order to make the accumulated water stored in the collecting groove 120 flow into the water utilization unit 20 for recycling treatment, the collecting groove 120 is provided with a water outlet 122 at one end in the longitudinal direction, when the accumulated water accumulates to the liquid level of the water outlet 122, the accumulated water flows into the water utilization unit 20 through the water outlet 122, the water utilization unit 20 comprises a water spraying assembly 210 and a water treatment mechanism 220, the water outlet 122 is arranged close to the water treatment mechanism 220, so that the water outlet 122 is arranged in communication with one side of the water treatment mechanism 220, the accumulated water directly flows into the water treatment mechanism 220 through the water outlet 122, after being treated by sedimentation and filtration in the water treatment mechanism 220, the accumulated water is used through the water spraying assembly 210, the second end of the water spraying assembly 210 is arranged to protrude from the ground, so as to irrigate the outdoor green plants or clean the dust on the ground.

[0035] It is worth mentioning that, since the present application is applied to a public toilet, the water droplets splashed and scattered on the surface of the water-permeable layer 110 after cleaning and washing are not too high in pollution degree, and therefore can be used for simple green plant irrigation after simple decontamination treatment.

[0036] As a preferred embodiment of the present application, a plurality of longitudinal ribs 121 are arranged in the collecting groove 120 in the transverse direction and divide the collecting groove 120 into a plurality of collecting sub-grooves 123.

[0037] It should be noted that the longitudinal ribs 121 can be used to support the water-permeable layer 110, so as to make the water-permeable layer 110 more stable, and at the same time, the collecting groove 120 is divided into a plurality of collecting sub-grooves 123, so that the accumulated water in different areas flows into the water treatment mechanism 220 through the respective collecting sub-grooves 123, therefore the water outlet 122 is arranged in each collecting sub-groove 123, preferably, the number of the water outlet 122 in each collecting sub-groove 123 is three, and the specific number can be set according to the width of each collecting sub-groove 123.

[0038] As a preferred embodiment of the present invention, the permeable layer 110 includes a plurality of permeable brick 111 units arranged side by side in the transverse direction, and each of the permeable brick 111 units includes a plurality of permeable bricks 111 arranged side by side in the longitudinal direction. The permeable bricks 111 extend in the transverse direction, and the two ends of the permeable bricks 111 are respectively placed on two adjacent longitudinal ribs 121.

[0039] It should be noted that the permeable bricks 111 can quickly absorb water on the ground and keep the ground dry, minimizing problems such as bacterial growth. The permeable bricks 111 are rough floor tiles with better anti-slip performance than ceramic tiles. In addition, there is no more water accumulation on the ground, which can reduce the risk of people slipping. When laying the permeable bricks 111, the permeable bricks 111 are extended horizontally so that their two ends can be respectively placed on the two adjacent longitudinal ribs 121, thereby using the longitudinal ribs 121 to maintain stable support.

[0040] As a preferred embodiment of the present invention, the water treatment mechanism 220 includes a water treatment tank 221 and two transverse partitions 222. The two transverse partitions 222 are arranged in the water treatment tank 221 at intervals along the longitudinal direction to separate the water treatment tank 221 into a sedimentation chamber 223, a filter chamber 224 and a treatment chamber 225 arranged side by side in the longitudinal direction. The top of each transverse partition 222 is provided with a plurality of seepage holes 2221 arranged at intervals along the transverse direction. The water outlet 122 is connected to the sedimentation chamber 223, and the first end of the water spray assembly 210 is connected to the treatment chamber 225.

[0041] It is worth noting that the water treatment tank 221 is used to receive the accumulated water flowing out of the collection tank 120 and serve as a container for water treatment, and the transverse partition 222 is used to separate the collection tank 120 into three chambers with different functions to form a sedimentation chamber 223, a filter chamber 224 and a treatment chamber 225 arranged side by side in the longitudinal direction. The sedimentation chamber 223 and the filter chamber 224 are respectively filled with sedimentation materials and filter materials, which can be activated carbon, sand and gravel, quartz sand, ceramsite, etc., and the sedimentation chamber 223 is a preliminary step in water treatment. The particle size of the material inside the sedimentation chamber 223 can be larger than that of the material in the filter chamber 224. The treated water is finally stored in the treatment chamber 225, and then water is directly taken from the treatment chamber 225 through the water spray assembly 210 for external vegetation irrigation and dust cleaning; and in order to facilitate the smooth flow of water between two adjacent chambers, a plurality of seepage holes 2221 arranged along the transverse intervals are opened on the top of each of the transverse partitions 222, so that after the water level in the sedimentation chamber 223 accumulates to the seepage hole 2221, it flows into the filter chamber 224 through the seepage hole 2221. Similarly, after the water level in the filter chamber 224 accumulates to the seepage hole 2221, it flows into the treatment chamber 225 through the seepage hole 2221, and the water in the treatment chamber 225 is directly sucked into the water spray assembly 210 through the first end of the water spray assembly 210.

[0042] As a preferred embodiment of the present invention, the water spray assembly 210 includes a water spray pipe 211, a water pump and a solenoid valve. The first end of the water spray pipe 211 is connected to the treatment chamber 225, and the second end of the water spray pipe 211 extends out of the ground. The water pump and the solenoid valve are both arranged on the water spray pipe 211.

[0043] It is worth noting that the water spray pipe 211 is arranged in a bent shape so that its second end can extend to the ground to facilitate spraying, and the water pump (not shown in the figure) is used to pump water, and the solenoid valve (not shown in the figure) is used to control the spray switch. These are technical means and technical combinations well known to those skilled in the art, so they will not be described in detail here.

[0044] Furthermore, a communication port 2211 is provided at the top of one side of the water treatment box 221 close to the water outlet 122 , and the bottom of the communication port 2211 is flush with the bottom of the water outlet 122 .

[0045] It should be noted that this connecting port 2211 is used to connect the water outlet 122 and the sedimentation chamber 223, and the bottom of the connecting port 2211 is set flush with the bottom of the water outlet 122. In this way, once the water in the water outlet 122 flows out, it flows directly into the sedimentation chamber 223 through the connecting port 2211. In this way, there is no need to add additional water pipes, saving materials.

[0046] Furthermore, the water-permeable layer 110 is tilted from an end away from the partition wall 30 toward the water utilization unit 20 .

[0047] It should be understood that when the permeable layer 110 is unable to absorb overflow water in time, the excess accumulated water can flow to the water utilization unit 20 through the slope, thereby further helping to reduce indoor water accumulation.

[0048] Furthermore, the slope of the permeable layer 110 is 1% to 3%.

[0049] It should be noted that, the greater the inclination gradient of the permeable layer 110, the easier it is for the overflow water to tilt and flow into the surface of the water treatment unit, but if the inclination gradient is too large, it will cause the user to stand unsteadily; if the inclination gradient is too small, the direction of the water flow is not obvious and the efficiency is low, so the inclination gradient of the permeable layer 110 can be set to 1% to 3%, preferably, it can be set to 2%, and those skilled in the art can set it according to the specific situation.

[0050] Furthermore, the cross section of the water outlet 122 is rectangular, and the longitudinal length of each water outlet 122 is 40 mm to 60 mm.

[0051] It can be understood that the larger the longitudinal length of the water outlet 122, the better the water outlet efficiency, but if it is too large, it will affect the structural strength of the collection tank 120. Therefore, in a preferred embodiment, the longitudinal length of each water outlet 122 can be set to 40mm~60mm, and technical personnel in this field can make a choice according to actual needs.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
